Question

A wave on a lake has a wavelength of 5.0 M and a Frequency of 4 Hz. What is the speed of the wave in m/s?

Answer 1

The appropriate speed will be "20 m/s".

Step-by-step explanation:

The given values are:

Wavelength,

λ = 5.0 M

Frequency,

f = 4 Hz

Now,

The speed of the wave will be:

⇒
`V=f* \lambda`

On putting the values, we get

⇒
`=4* 5.0`

⇒
`=20 \ m/s`
